Requirements

Installation

Or if you want to install directly from the repository: python setup.py install, or drop the pysolr.py file anywhere on your PYTHONPATH.

Usage

Basic usage looks like:

# If on Python 2.Xfrom__future__importprint_functionimportpysolr# Setup a Solr instance. The timeout is optional.solr=pysolr.Solr('http://localhost:8983/solr/',timeout=10,auth=<typeofauthentication>)# How you'd index data.solr.add([{"id":"doc_1","title":"A test document",},{"id":"doc_2","title":"The Banana: Tasty or Dangerous?","_doc":[{"id":"child_doc_1","title":"peel"},{"id":"child_doc_2","title":"seed"},]},])# Note that the add method has commit=True by default, so this is# immediately committed to your index.# You can index a parent/child document relationship by# associating a list of child documents with the special key '_doc'. This# is helpful for queries that join together conditions on children and parent# documents.# Later, searching is easy. In the simple case, just a plain Lucene-style# query is fine.results=solr.search('bananas')# The ``Results`` object stores total results found, by default the top# ten most relevant results and any additional data like# facets/highlighting/spelling/etc.print("Saw {0} result(s).".format(len(results)))# Just loop over it to access the results.forresultinresults:print("The title is '{0}'.".format(result['title']))# For a more advanced query, say involving highlighting, you can pass# additional options to Solr.results=solr.search('bananas',**{'hl':'true','hl.fragsize':10,})# You can also perform More Like This searches, if your Solr is configured# correctly.similar=solr.more_like_this(q='id:doc_2',mltfl='text')# Finally, you can delete either individual documents,solr.delete(id='doc_1')# also in batches...solr.delete(id=['doc_1','doc_2'])# ...or all documents.solr.delete(q='*:*')

Multicore Index

# Setup a Solr instance. The timeout is optional.solr=pysolr.Solr('http://localhost:8983/solr/core_0/',timeout=10)

Custom Request Handlers

# Setup a Solr instance. The trailing slash is optional.solr=pysolr.Solr('http://localhost:8983/solr/core_0/',search_handler='/autocomplete',use_qt_param=False)

If use_qt_param is True it is essential that the name of the handler is exactly what is configured
in solrconfig.xml, including the leading slash if any (though with the qt parameter a leading slash is not
a requirement by SOLR). If use_qt_param is False (default), the leading and trailing slashes can be
omitted.

If search_handler is not specified, pysolr will default to /select.

The handlers for MoreLikeThis, Update, Terms etc. all default to the values set in the solrconfig.xml SOLR ships
with: mlt, update, terms etc. The specific methods of pysolr’s Solr class (like more_like_this,
suggest_terms etc.) allow for a kwarg handler to override that value. This includes the search method.
Setting a handler in search explicitly overrides the search_handler setting (if any).

Custom Authentication

# Setup a Solr instance in a kerborized enviornmentfromrequests_kerberosimportHTTPKerberosAuth,OPTIONALkerberos_auth=HTTPKerberosAuth(mutual_authentication=OPTIONAL,sanitize_mutual_error_response=False)solr=pysolr.Solr('http://localhost:8983/solr/',auth=kerberos_auth)

# Setup a CloudSolr instance in a kerborized environmentfromrequests_kerberosimportHTTPKerberosAuth,OPTIONALkerberos_auth=HTTPKerberosAuth(mutual_authentication=OPTIONAL,sanitize_mutual_error_response=False)zookeeper=pysolr.ZooKeeper("zkhost1:2181/solr, zkhost2:2181,...,zkhostN:2181")solr=pysolr.SolrCloud(zookeeper,"collection",auth=kerberos_auth)

If your Solr servers run off https

# Setup a Solr instance in an https environmentsolr=pysolr.Solr('http://localhost:8983/solr/',verify=path/to/cert.pem)

# Setup a CloudSolr instance in a kerborized environmentzookeeper=pysolr.ZooKeeper("zkhost1:2181/solr, zkhost2:2181,...,zkhostN:2181")solr=pysolr.SolrCloud(zookeeper,"collection",verify=path/to/cert.perm)

Custom Commit Policy

# Setup a Solr instance. The trailing slash is optional.# All request to solr will result in a commitsolr=pysolr.Solr('http://localhost:8983/solr/core_0/',search_handler='/autocomplete',always_commit=True)

always_commit signals to the Solr object to either commit or not commit by default for any solr request.
Be sure to change this to True if you are upgrading from a version where the default policy was alway commit by default.

Functions like add and delete also still provide a way to override the default by passing the commit kwarg.

It is generally good practice to limit the amount of commits to solr.
Excessive commits risk opening too many searcher or using too many system resources.
